style(waybar): swap obvious literal labels for Nerd Font glyphs

Numeric/identity labels stay (CPU, MEM, °C, network arrows, clock).
Iconic labels are replaced with codepoints from ttf-noto-nerd:

  battery       BAT/CHR/PLG  -> nf-md-battery_*, _charging, power_plug
                               (U+F0079..F0084, U+F06A5)
  pulseaudio    VOL/MUTE     -> nf-md-volume_low/medium/high/off
                               (U+F057E..F0581)
  bluetooth     BT on/off    -> nf-md-bluetooth/_off/_connect
                               (U+F00AF/B0/B2)
  idle_inhib.   INH/IDL      -> nf-md-eye_off_outline/_outline
                               (U+F06D1, F06D0)
  custom/wifi   text only    -> prefix nf-md-wifi/_off
                               (U+F05A9, F05AA)
  custom/webcam CAM          -> nf-md-camera (U+F0D5D)
  custom/notif. NTF          -> nf-md-bell_outline/_check_outline/_ring
                               (U+F009C, F11E8, F009E)
  custom/tb     MAIL         -> nf-md-email/_alert (U+F01EE, F0D42)

style.css font-family widened from 'mono' to a declarative fallback
chain so glyph rendering doesn't depend on fontconfig auto-fallback.
